It will at least eliminate people who commit in unrelated projects.

I didn't know this builder would test flang as well: which stage of the
build is doing so?
In general I try to keep builder configs more focused to avoid that bug in
one components hides regression in another one (for example MLIR breaking
stage1 for this bot for a day and in the meantime you get a stage-2
regression that won't be detected)

In any case, this will still help people contributing outside this list
(libc++, lldb, lld, compiler-rt), unless you also need these.
